Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468224, here are decompositions:
- 13 + 31468211 = 31468224
- 23 + 31468201 = 31468224
- 127 + 31468097 = 31468224
- 157 + 31468067 = 31468224
- 197 + 31468027 = 31468224
- 211 + 31468013 = 31468224
- 223 + 31468001 = 31468224
- 241 + 31467983 = 31468224
Showing the first eight; more decompositions exist.
